ROCKING CH'URN.

SPECIFICATION forming part of Letters Patent No. 737,047, dated August 1603. A

Application filed March 9,1901. Renewed April 6,1903. Serial N01 151,411. (No model.)

I To all whom it may concern:

" a specification.

Be it known that I ,-LAMMERT VAN OLST, a citizen of the United States,residin g at Orange 1 City, county of Sioui', State of Iowa, have in-- vented certain new and useful Improvements in Rocking Ohurns, of which the following is My invention relates to rocking churns, such as are adapted to be operated either singly or by a rocking-chair.

One object of the present invention is the provision of a churn which can be readily attached to and detached from the rockingchair, so that the chair can be detached and used as a rocker when the'churning operation is not going on or to permit the operation of. the churn by hand. V 5

A further object is the provision of a novel rockingframe construction for removably holding the churn-body, so that the lattercan be taken out for any purpose or replaced by another churn-body. V

A still further objectv is the provision of a novel construction of dasher which can be readily placed in the churn-body or removed and of such arrangement that it can befoldedinto compact form.

Having the foregoingobjects'in view, the invention consists of a rocking churn com prising certain improved features and novel combinations of parts, more fully set forth in the following description, and recited in the appended claims. Y

In the accompanying drawings, Figure 1 is a perspective view of the complete invention 5- Fig. 2, a detail of one of the connections between the rocker and the frame; Fig. 3, a

' perspective view of the churn-body with parts broken away to disclose the manner of securing the dashers; Fig. 4, a detail of another form of dasher; Fig. 5, a detail of another modified construction; Fig. 6, details of the joints of the dasher, and Fig. 7 a detail of the dasher when folded or collapsed.

The rocking; frame 1 is made of slats in skeleton form and preferably provided with a handle tube, by which it can be manipulated when it is desired to dispense with the rocking-chair 3, which is employed to operate the churn; One of the rockers of the chair has apertures at extending transversely therethrough which are coincident with correture. per part of the rocking frame and held theresponding bolts 5 onflone of the rockers of the through the apertures and the rockers of the chair secured rigidly to the rocker of the frame, both the rockerof the chair and the rocker of the frame being of the same curva- The churn-body 6 is located in the upin in a removable manner by a hinged slat 7, secured by a fastening 8. The body is thus rendered readily removable. It is preferably provided with handles 9 and a faucet 10 at itslower portion, the faucet serving to drain off the milk to leave the butter in the churn for the washing thereof by the addition of water through the top 11, which is depressed and provided with a suitable cover.

Any of the types of dashers shown maybe employed, the preferred construction beingthat illustrated as in position in the churn-body.

This consists of blades or paddles 12, cut away at their ends 13 and at their centers 14, where they overlap, and pivotally secured together at their ends and centers by the respective removable pins 15 and 16. Thepaddles are provided with apertures 17 and at their points and secure the bar 19, madein two parts hinged together at 20'and provided with depending flanges 21 adjacent its ends. The ends of the fastening-bar 19 are received in apertures 22 of upright cleats 23, located against opposite sides of the churn-body.

In introducing the dasher construction previously described into the churn-body the of intersection are notched at 18 to receive dasherblades are collapsed or folded together to assume the form shown in Fig. 7 and thus made into convenient size for introduction into the opening in the body, after which they are stretched out, and the fastening-bar 19 is fitted inthe notches 18 and its ends in the apertures 22, the depending flanges 21 going. inside of the angles at the ends of the extend ed dasher construction and preventing the collapsing thereof.

erence of about one-half the height of the churn-body;

In the construction shown in Fig. 4 notches 18 are employed, as before, as also the, cleats and the fastening-bar; but the crossed arrangement of the paddles or dashers is omitted, and they are only hinged at their ends.

The dashes are by pref- In the modified construction as shown in Fig. 5 the notches 18 are also employed, and I have illustrated a unit of the dasher construction used, which consists of curved paddles 24, connected at their ends and held apart by a cross-bar 25, so as to assume a substantially elliptical shape. As many of these units are employed as are found necessary and )laced side by side on the bottom of the churnbody and there held in a connected series by the engagement of the fastening-bar 19 with the notches 18.

The churn-body having been placed in the rocking frame and secured by the hinged gate or slat, said frame may be rocked by manipulating the handle. As a pleasant wayof performing the churning operation it is frequently more desirable to couple the rocking churn direct to the frame, and the operator can then occupy the chair and rock back and forth. Owing to the simple connection be tween the chair and the frame, detachment can readily be had and the chair used about the house as an ordinary rocking-chair, and I thus make provision for a light, simple, and novel construction which possesses decided advantages over the cumbersome and bulky forms of l-ockingchair-operated churns heretofore known to the art.

I am aware that changes of construction could be resorted to without materially changin g the form or detracting from any of the advantages of theinvention, andI do not, therefore, limit myself to the precise construction herein shown and described, but consider that I am entitled to all such modifications as fall fairly within the spirit and scope of the invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a churn,the combination with a churnbody, of a dasher composed of paddles or members connected together and removably positioned in the churn-body, and an independent fasteningbar composed of two parts hinged together and each provided with a flange, said fastening-bar having its ends detachably engaged with the sides of the churn-body and its flanges engaged with the paddles or members, and holding the dasher in position in the churn-body. I

2. In a churn,the combination with a churnbody, of a dasher composed of paddles or members connected together and provided with notches in their edges and removably positioned in the churn-body and an independent fastening-bar received in said notches and connected to the sides of the churn-body, whereby the dasher is-held in position.

3. In a churn,the combination with a churnbody, of a dasher composed of paddles or members hinged together so as to be adapted for extension or collapsing, and means for securing the dasher in extended arrangement in the churn-body.

4. In a churn,the combination with a churnbody, of a dasher composed of paddles or members hinged together and adapted for collapsing or extension, and a fastening-bar connected to said paddles for holding them in extended arrangement in the churn-body.

5. In a churn,the combination with a churnbody, of a dasher composed of paddles hinged together at their ends and provided with notches in their upper edges, and a fasteningbar lying in the notches and having its ends secured to the churn-body,whereby the dasher is heldin extended arrangement.

6. In a chu rn,the combination with a churnbod y, of a dasher composed of paddles or members hinged together, cleats at opposite sides of the churn-body, within the same, and a fastening-bar engaged with the paddles to hold them extended and having its ends engaged with the cleats.

7. In a churn,the combination with a chu rnbody, of a dasher composed of two series of paddles each formed of members hinged together, said series crossing and recrossingeach other and pivotally connected at their points of intersection, and means for securing the dasher in the churn-body.

8. In a churn,the combination with a churnbody, of a dasher composed of two series of paddles each formed of members hinged together, said series crossing and reerossingeach other and pivotally connected at their points of intersection, and a fastening-bar extending across the dasher and engaged with the churnbody, which is provided with flanges or members adapted to engage the dasher to prevent contraction thereof.

In testimony whereof I hereunto affix my signature in presence of two witnesses.
